You have it totally backward. Look at modern Catholic Churches and they are lacking in the imagery while the Church of Old was packed full of them. Now which one do you thing was the bigger problem.
I am sure you don't need me to help cure that bit of wonder.
Backwards? Hardly.
As I have said for the umpteenth time, the early church was not adverse to art in and of itself. There are many examples of pre-Nicene art.
The ECF's were opposed to giving reverence to religious art/images, or giving reverence to what the art/images represented.
Bit of Wonder? Oh, I am fully clear on this matter. Now that I have hopefully taught you the truth of the matter on this, you will be fully clear on it as well and not stuck in wonderment... or wonderland.
